Etherape might be a useful tool also.
http://etherape.sourceforge.net/
It has a graphical 'radar display' of traffic to/from network hosts.
I have found it very useful in the past for monitoring/debugging.
I'd hazard a guess though that in a cluster on full song you'll get a
busy display, but you should be able to spot any 'hot' nodes.
